i have an image which has 2 colors, black and white.
i wish to get a region object that has all the white areas 'selected'
the shape is not just a polygon, its fairly shapeless
is this the best approach: create a region that is the size of the image and run a loop checking each individual pixel to see if its black, if it is then exclude it from the region. (i've got a feeling this will take very long to load)
Following my test project for making a map editor, I finally got the tile selection part covered.The application can already tell which tile(s) is selected.
So now we will work on "click the map and the tiles will be drawn" part.
When the user clicks the map, I need to "copy" a selected tiles in the tile selector, and "paste" them on the map. The process is a bit longer actually.Or is there a way to directly copy the selected tiles to the map image?
What i'm trying to do is fill a non rectangular region (actual build up out of 6 points) and draw a bitmap in such a way that it stretches with the region. Now for drawing a normal bitmap or even a trapezoid bitmap there are examples on the net. but drawing anything more then that with GDI+..

(1) Is this the correct approach?
(2) If so, how do I get the outline of the region so I can call DrawPath?
how can i get the points which make a polygon from a region which was derived from the polygon's points?

View 5 RepliesImagine you want to draw a regular shape such as a triangle, rectangle ... all the way up to say a 10 sided figure ( a decagon ) or more. I know that when we try lots of sides it looks closer and closer to a circle or an ellipse. The problem I am thinking of is placing smaller circles ( or ellipses ) at the correct positions near the points of that shape as shown for a triangle below.Here comes the question(s) How could we: a) Correctly place the circles ( or ellipses ) at the points so that the sides are at a tangent to them andb) Can we combine the REGIONs of these to produce a figure with rounded points so the light blue bits get excluded? I guess that to produce a method to deal with all the mathematics involved would be quite a complex task.Has anyway previously tackled doing this or know of any .Net tools I could use for this problem?

View 6 RepliesI have a Rectangle (the class) that I'm using to define a region on a form and when the mouse enters that region it shows 2 buttons (which are on the form and within the bounds of the rectangle) and I would like the buttons to remain visible when the mouse is over either of the 2 buttons then when the mouse leaves the region or leaves the form they are set to invisible again. Here's the code I have so far:
[code]....
The problem is when the mouse enters the bounds of the button, the form's MouseLeave event fires and thus my buttons are hidden which means the user can't click either of them either.
I don't know if this is possible, but I want my form to be 'window-blocking', just like the taskbar, when a window is maximized, it won't overlap the form.
